Enamel flux is different to the flux used in soldering - it is a term used to describe transparent, colourless enamel. Enamel flux is used as an initial background layer (particularly when working on copper), as it absorbs oxides from the backing metal. This reduces the risk of oxides feeding through to later layers of enamel and therefore helps to preserve the vibrancy of enamel colours when they are fired above it. Enamel flux can also be used as a backing to secure cloisonne wires and embellishments, and is frequently used as a final 'top coat' for enamel work to protect the colours and designs underneath.
